In general, wisteria is a low-maintenance plant, but in order for it to retain its richness over the years, it should be pruned twice a year.
Fall or early winter pruning of wisteria helps straighten out rapid summer growth and certainly makes early spring pruning easier. In addition, regular pruning of wisteria encourages flowering. What you have to do is cut off the current season shoots up to three buds from the base. These will then bear the new shoots and flowers of the following season.

How and when to prune a wisteria?
In January-February, cut the side shoots of the wisteria even further – 6-10 cm long, leaving only two or three buds on the side shoot.
Both of these prunings should be done annually. The only shoots that should be left are those needed to expand the size or direction of your wisteria. Any lateral formation of the new lateral structure should be done at this time unless it was completed during the fall pruning session.
Don’t forget to prune your wisteria in the fall, followed by a severe pruning of your wisteria at the end of winter. This will help control growth and focus all the plant’s energy on the flower buds, near the main stem.

Should the pods of a wisteria be cut?
Like other flowering plants, wisteria reproduces through seeds. When the fragrant flowers eventually wilt, they give way to long pods that contain the seeds, which literally explode on the ground and give rise to new plants. It is usually in late summer or early fall that you may notice pods appearing on your wisteria that look like oversized green beans or snow peas.
It’s up to you whether you want to remove the pods or leave them on the plant. Still, keep in mind that in the spring the seed pods can block the view of the flowers, and you may want to remove them before they bloom. So, it is better to remove them when doing winter pruning. So you won’t have any pods if you cut off the top of your wisteria after it blooms.
Glycine is poisonous. Children or pets (or any other animals) should never be allowed to eat any part of the plant, especially the pods.
